SPECIFICATION forming part of Letters Patent No. 319,301, dated June 2, 1.885.

Application filed May 5, 1884.

To all whom it may concern:

Be it known that I, SAMUEL E. MOWER, of

"New Haven, county of New Haven, State of Connecticut, have invented an Improvement in Machines for Manufacturing Hair-Pins, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention has for its object the construction of a novel machine for the rapid production ofhair-pins having either spirally-twisted or straight legs.

In'my improved machine the wire, taken from a reel, is fed into grooves of a wire-carrier (shown as a cylinder) and cut off of the proper length. The pieces of wire, as the carrier is moved intermittingly, are presented successively to the action of point-forming devices, and are then struck centrally by a driver-bar or plunger and forced through a die or former, which gives to the wire the shape desired for the pin to be produced.

Figure 1 is a plan view of my improved machine for making hair-pins; Fig. 2, a side elevation of Fig. 1, looking at it in the direction of the arrow in Fig. 1; Fig. 3, an opposite side elevation of the same; Fig. 4, a rear elevation; Fig. 5, a detail showing in elevation the feed-rolls and some other parts to be referred to; Fig. 6, a front elevation and a longitudinal section of the die or former shown in Fig. 3; Fig. 7, a modified form of die or former. Fig. 8 shows a hair-pin such as may be made in the machine herein described; Fig. 9, a central longitudinal section of the wire-carrier; Fig. 10, details of one of the wire-pointing spindles, and Fig. 11 an enlarged detail of the end of the driver.

The frame A, of suitable shape to support the working parts, is provided with a driving'shaft, a, having a belt-pulley, of, from which motion is conveyed to the shafts a a of thefeed mechanism (shown as rolls 1) 11'.) through the train of gears a, a, a a, and a, the latter two being respectively on the shafts a a, to which the said feeding-rollers are attached.

The feedingrollersb 1), (shown in detail in (N0 model.)

Fig. 5,) arranged in the case 12*, attached to the frame A, operate to feed the wire to into the machine. The rollers b b are cut away longitudinally, as at I), or shouldered, so as to leave an acting surface, b which shall be equal in length about the roll to the length of 5 the wire to be fed between them at each rotation thereof, the length of the surface b depending on the length of the pin to be made. The rolls draw the wire intermittingly from a suitable reel, and in practice will draw the same Co through a suitable wire-straightener. (Not shown.) On the way to the feed-rollers the wire w is passed through'a groove in the ear of a plate, b, secured to a bracket, 1), attached to the case b, and between a serrated annulus, b 6 5 loose on a stud, 6 of the said bracket b, and a serrated bar,-b ,placed above on thesaid serrated annu1us,bein g held to the bracket in an inclined position with relation to the annulus, and acting to, restrain the movement of the annulus in opposition to the arrow thereon, Fig. 5, but permitting it to be moved freely in the direction of the said arrow as the wire is fed into the machine, such devices serving as a stop or check to preventbackward movement of the 5 wire. Beyondthe feed-rolls b b the wire 10 is passed through a tube, 2) connected with the case b?, as clearly shown, in Fig. 5, and from the said tube the wire is passed into one of the longitudinal grooves, 0, cut in the face of the So wire-carrier C, (shown as a cylinder,') (see Figs.

1 and 2,) until the end of said wire projects beyond the opposite side of the said carrier, when a circular cutter, 2, is forced against and severs the wire at the delivery end of the 8 5 tube b The cutter 2 (see Figs. 3 and 4) is secured to a slide, 3, held in a rigid part of the frame, and the slide is moved by the pivoted lever 4., having a roller stud or pin, which enters the 0 cam-hub 5 on the shaft (0. The pivoted lever 4 has an adjusting screw, 52, which abuts against the end of the slide 3, to regulate the throw or movementof the slide-bar carrying the circular cutter. A suitable coiled spring 9 5 (not shown) will be inclosed within the frame. A, back of the slide 3, and, engaging a stud on said slide-bar, will withdraw the circular The shaft of th transversely-grooved carrier 0, held in the frame A, is provided with a fixed ratchet, 0 which is engaged and rotated by a pawl, c, on a pawl-carrier, c ,'hav iiig itsfiilcruih on the shaft 0, and pfovide'd at its lower end with a roll,- 0 whichrriin's upon the cam-wheel d, made fast to the shaft d, the latter having a bevel-gear, d*, which is engaged by the bevel-gear cl on the drivingshaft a, the whole operating to move the carrier O intermittingly for a sutficient distance to successively bring the transverse grooves c of the carrier in line with the bore of the tiibe' b, to permit the wire to be fed through it and into the grooves c. v a

A coiled spring, 6, attached to the frarneA and to the pawl-carrier c serves to hold the roll am eng'ageinent with the cam-wheel d; An adjustable stop-str et; e in the st'u'il fastto the franie A, lifnit's the movement ofthe pawl-carrier in the direction ofthe spring a.

The carrier 0 is provided" with an annular grbete iiear thecente'r of its length, leaving merely the sinall hub cf, which enciicles the shaft 0; asin'dicated in Figs, 3 and A wire- "oft, f, made as a sector, partially surroiih'ds thesaid hiib *0, and has its periphery shbstantiall y flush or even with the b ttoin, of the groov'es c in saidca'rrier, as shown in Fig. 3; the'said support f being secures in fixed petites by e set-s'e'r'ew, f, assed through the e t'hterstnk and slotted portibnf of the said support, and into the die or fornier holding pest}: which in turn is placed in the annular gre 've etc into the said carrier, and is fii'inl'y fasteiied to the frame A. A g

A spring'gui'de, 8, is attaehed to the rear of the support f by screws 22 at a paint oppositewhere the wire at is fed into the grooves of the carrier, so as to guide the w re into the grooves at that end of said earl-let farthest re moved from the feed-rolls", the sprihg -g'uide allowing the wire to be taken froth beneath it The mouths of the grooves ihay be ihade flaring; if desired, to faeilita'te the passage of thewir'e into them.

Hoods 9, attached at their rear ends to the frame A by bolts isurretnu the grooved riphery of the carrier C, and slotted brackets g, ecured to the free ri-ent ends of the said hoods, receive screw-th readed rods 9 ,seetreu to the frame-work, and thumb-nuts g on the said rods 9 enable the hoods to be held more or less closely against the grooved periphery of the carrier, thereby generating sufficient friction to prevent any backward ifio'vehient 'o'fjthe jcai'ri'er, which may be induced by the pawl 0 moving over the ratchet 0", and also retaining the wires in the grooves e thereof.

A spring-presser, 72", attached "to a strip, h, secured to the hoods, extenueuelengateve the upport f, (S66 Fig. age-nu has a clamping-blo'ck, h fastened to its forward or free end. This block is actedupon bye. lever, i, seeureu' toj r'ock-shaft, r, held, in bearings r 1 giiidewayaBflof the heme-work, sustain wirepointing spindles 7r, provided with pulleys k,

which receive suitable belts, by which to rotate them, the belts being preferablypperated by independent pulleys on a s'tiittble v shaft overheador at-the eiling, the said spindles in practice having a speed of about two tho'uterm-gee the contested by links s withpin's apps-site sides, and near opposite ends of the lever i, the latter in its vitre ieiis moving the eatriages B simultaneously in and out to force the ends of the pointing-spindles against the ends of the wire (shown by. heavy black lines) p'rbje cting beyond the end's'pf the eartier; As the carriages are moved forward the pointing-spindles, recessed at their inner ends, (see Fig. 10,) pass over the ends cf the wire, and flitting-blades t onein each spind'le' act to point the wire; The spindles 7c are free to slide in their bearings ill'fille carriages-,and

are urround d by spiral springs k which latter enable the spindles to stop when the points of the wire strike the rotating blades 25,

notwithstanding the cairiages continue toniove toward the earner O. The pointingspindles ate thus held against the wire to be pointed by a yielding or spring pressure. I,

Referring to Fig. 3-, 0 represents a spirallygree'veu die 'or foriner firmly held in a slptin the die-holding postf by meansof an adjns'ting screw-bolt, 0, it holdingthe die in the line of the longitudinal axis of the reciprocating driver-bar p. The driver -bai'p,notehedatp,

(see Fig; 11,) is passed through a guide, 10 seetreu to the post f and the rear end of the said driver-bar is extended through acrosshead, 7", in whieh it is retained loosely by the toners '9 oetteeheu to the driver by suitable screws; The crosshead r is re'ciprocate'd in sate fi'y'e hundred rotations per minute, These the ways 11 of the frameA 'bynieans or the connecting-rod 1 fastened to the cross-head and to the disk 1 on the shaft 6', h ereinbefore mentioned. If desired, the spirally-grooved tiibe may be Torined, as shown in Fig. 6, by nieans' of spiral plates held'in a smooth-bored tube by means of sc'frews, the spaces between I the plates forining thegrooves, and, further, a straight gretve, is cut-acrossthe face of the tube to aid in holding and guiding a wire when being for'ce'd into the tube.

The outer or rear end of the driver-bar is provided with a notched block, 16, which, in the return-stroke of the driver-bar, engages the wedge-shaped block 17 ,secured to the post 18, to insure the proper position for the notched front end of the driver-bar when it is again started forward to engage the wire, which latter is held across the opening at the mouth of the die or formerby means of springs 1 connected with the hoods g g at either side of the die or former 0. (See Figs. 2 and 3.)

By the partial rotation of the carrier a wire retained in one of the grooves c is brought across the opening of the die or former 0, in which position it is heldby the springs t 1111 til, by the forward movement of the drivere harp, the wire is caught at the middle of its length by the notched endof said driver, and is bent and forced into and through the spirally-grooved die or former, the driver during each operation being rotated by the action of the wire in the spiral groove of the stationary die, thus producing a spiral hair-pin, which, upon the return of the driver, is stripped froui the latter and drops into a suitable receptacle provided for that purpose. I

If a common straight hairpin is to be formed, the grooves in the die orformer will be straight, instead of spiral, as'in Fig. 7. The machine is so speeded that the feed-rolls feed'a length of wire to the grooved cylinder or carrier while the latter remains at rest, and the wire having been fed into the said grooves, the circular cutter is moved and actuated to sever the wire.

When the feed mechanism supplies one groove with wire, the ends of a piece of wire previously fed into and yet held in one of the grooves of the carrier, and held clamped therein, are being pointed, and at the same time yet another length of wire is being forced into the former 0 by the driver p to complete a hair-pin.

As the carriages B are moved baekward,the presser h is lifted, and immediately thereafter the carrier is moved forward to bring an unfilled groove, c, in line with the tube b ",which having been done,the feed mechanism is operated to move the wire, the slide 3 is retracted or drawn back to remove the circular cutter2 from the end of the tube b and as soon as the said empty groove of the carrier has been filled the slide 3 is moved forward to cut off the wire, and the carrier is again moved forward one step.

Instead of the rollers b b, for feeding the wire intermittingly into the grooves c of the carrier, any other usual or suitable wire-feeding mechanism might be employed.
